I want to try that, this way I get to have babys only once and not 50 times later and then I have 200+ guppysJunne said:Welcome to FL
I'd also say 10 gallons. Do you already have them or getting them? If you have not gotten them yet, make sure you get males ( females will come from the store pregnant ) and then you will have to deal with 20 + fry each litter.
Besides, male guppies are prettier
